Can Blender 2.79 Fluid Physics act on Rigid Body objects?
Yes!!!
After 2 days of work, I can finally say: It is Possible!
See the picture below.

You can watch the full animation Here on Youtube 11s Video
By the way, no it is not a keyframed animation of the turbine that you are seeing. It is pure physics.

The author wrote under the linked youtube video:

In Blender, Rigid Bodies effects on Fluids are very to implement. However, for long, the reverse interaction was dubbed impossible. No more! Using Blender Particles to emit particles, then converting them to rigid bodies and finally applying Cube Suffer on the resulting animation.
In this video, I'm using a modified version of Cube Surfer to make able to utilize simple meshes (not particles as in the original version).
If there's enough likes, I might post a detailed tutorial.
